30,000 Sq ft Cat B fit-out by Loop interiors. The centrepiece of the refurbishment was a groundbreaking spiral staircase manufactured and built entirely M-Tech Engineering's factory in Nottingham in sections that could be transported through a standard front door. The staircase was then dismantled and transported to Germany where the internal balustrade, the balustrade to the first floor and the underside were clad in form following walnut veneer, along with the handrail. The balustrade to the outside was manufactured in mild steel and then coated in liquid bronze.
The staircase was manufactured in a way that no fixings are visible. The treads and risers are manufactured from Carrera marble.
This staircase is the first in the World to be manufactured using this process.
